APPARATUS FOR THE MAN-UACTURE OF AIR-GAS.

SPECIFICATION forming part of Letters Patent No. 280,201` dated June 26, 1883. Application filed September 25, 1882. (No model.) Patented in Queensland May 15, 1882.

To all whom it may concern:

Be it known that I, DANIEL HOWARD MAR- 'TIN, of Ipswich, in the British colony of Queensland, machinist, have invented new and use-` ful Improvements in Apparatus for the Manufacture of Air-Gas, (for which Ihave obtained Letters of Registration in the said British colony of Queensland, dated the 15th day of May, 1882,) of which the following is a specication.

My invention consists of certain i1nprove ments in apparatus for the manufacture of airgas, by which I am enabled to produce such apparatus in a compact and serviceable form, capable of cheaply and safely manufacturing large quantities of gas at a low rate, and of automatically regulating such manufacture, so that no'large quantity is held in storage;

In my apparatus, there are four main partsnamely, air-suppliers, a gas-generator or aircarburetor, a gas-holder, and a gasolinereservoir. TheMair-suppliers consist of two doubleacting bellows, which supply four overlapping currents of air to the gas-generator or carburetor. The gas-generator or 'carburetor is a comparatively shallow chamber underlying the whole ofthe other parts of the apparatus. The gas-holderis of ordinary construction, and is not of use for its storage capacity so much.

as for its automatically regulating the manuA facture of the gas as it is required. The gaso line-reservoir is a chamber connected to the generator by an elbow-pipe in which is a cock.

This reservoir may be made removable at will, or a permanent part of theapparatus. Each arrangement has its advantages. If it is made removable, it is more convenient in one sense, because it may consist of an ordinary gasoline drum, and when empty it may be rci placed by a full one, and on the other hand it is made a permanent part of the apparatus, if a safety-pipe may be inserted to conduct any gases from the top of the gasoline-reservoir to a point below the Water in the gas-generator. The supply of gasoline is controlled by a loatvalve in the generator, and the supply of air thereto is controlled by cocks movable by hand, y

and connected by a rod to the stoppinggear. Opening or closing thesecocks automatically starts or stops the working of the machine. The gas-holder, to which the stopping-gear is connected, rising and falling, has the same effeet. The air-suppliers are driven by a weight, as is well understood.

In order, however, that my invention may be distinctly understood, I will now refer to the drawings hereto attached, in which- Figures l and 2 show end elevation and plan, respectively, of one of my air-gasmaking machines with the gasoline-reservoir removable. Fig. 3 is a longitudinal sectional elevation of the saine. Fig. 4 is aplanview ofthe crank-shaft and its pinion, from which my airsuppliers are worked, and Figs. 5, 6, and 7, plan, side view, and end view, respectively, of my stopping-gear, as hereinafter more particularly described. Figs. 8 and 9 show detail views of my gasoline-valve. Fig. 10 shows the gasoline-reservoir as constructed when it is a permanent part ofthe apparatus, with the safety-pipe G'i in it, ashereinbefore described. Fig. l1 is a detail perspective ofthe stopping mechanism.

A 'and B are the air-suppliers, connected by rods A and B to the crankshaft C', A'y B2, the air-pipes leading into the generator D.

A5 A5 are blocks iixcd to the side of the tank, or otherwise suitably held, and the top and bottom boards of bellows A are secured to said blocks. BB are also blocks fixed to the apparatus, and by means of which the out side boards ofthe bellows are secured. It will thus be seen that the outside boards of each bellows are firmly secured, while the center piece in each is free to vibrate in response to the crank-rods A B.

Afi B3 are the cocks connected to rod E, for

opening and closing the supply of air to the generator by means of handle E'.

F is a pipe for the passage of the air-gas to the receiver I-I, from whence it passes, through -perforations I-I7 in disks II and H2, into the gas-holder H3. II4 is a tank for holding same. H is a guide for gas-holder; I, radiusbar liked to gas-holder; I and I2, levers on one pivot, I. To I2 is attached rod or wire 1*, workl ingthe stopping-gear J.

Gis a pipe for supplying gasoline from its reservoir G to generator D. G2 is a cock therein, and G3 float for closing valve G* (of the section shown in Fig. 8) on seat G5.

H6 is the gas-supply pipe to burners."

F is the cock in pipe F. Ihis cock is connected to rod E.

On the crank-shaft C is pinion Cwheel C5, provided with counterbalance-weight C, and arms G. The weight C3 acts as a counter-balance for the crank GS. The pinion C2 is driven by large spur-wheel IQ on drum-shaft K', I,

being the drum on which the rope or cord is wound,which, after passing over suitable pull leys,(not shown,) terminates in a weighnas is well understood.

D is a drawing-off cock, aud DAZ a gage.

C is the main framing.

rIlhe stoppinggear consists of frame J, on which is pivoted iiat bolt J having a slot, J 2, in which trigger J works. JT is a spring bolt ed to the frame J and pressing against trigger J 3 at the oth er end. A second bolt, J 4, pivoted under the frame, is actuated by a spring, J5, and controlled by projecting piece F2 on rod E. XVhen the machine is working the ends of the arms Cl are free to pass through an opening, J 5, in the bolt J. r

rlhe mode of operationis as follows: The gasholder tank H'L is first filled with water then the generator I) is supplied with water-say to level of dotted line d, Fig.YV 3 and then the cock Gr2 is opened, so as to supply the gasoline through valve G until that supply is cut off by iioat G at about dotted line d', same figure, the level of which will also be seen by the gage D2. The cocks A3, B, and F are then opened by handle FJ, the air-suppliers set to work so as to force air in successive currents down pipes A* and I3, which discharge underneath the water-level, through which and through the gasoline above it they ascend, becoming carbureted or converted into air-gas in their passage, and finally entering,through pipe F, into receiver H, and it is then conducted to the burners by pipe H, or through perforations in thedisks H and Hl into the holder H3, to act as a means for regulation, thus: Then this holder rises up the radius-bar I, levers I and I2 and rod I'L pull the trigger J i ofthe stoppinggear,which, springing over, moves the bolt J and so carries the slot J beyond the line of travel of the arms C", which thus stops the motion of the crank-shaft, and consequently suspends the operation of manufacturing gas until the gas-holder falls again and then the automatically reverse action of the trigger J 3, moving the bolt J back again, allows the arms C* to pass through the slot J 6, and so resume the manufacture of gas. Then the handle E is moved to open the cocks A3, Bi', and F', the projecting piece F on rod E shoots the second bolt J t out of the line of travel of the arms C", thus allowing them to revolve and the manufacture to proceed. On the reverse movement of the rod E (when closing said cocks) the projecting piece E2 allows the spring J to shoot the bolt J within the line of travel of arms C, thus stopping the manufacture of gas, as before described. The motive power therefore cannot revolve the shaft K when the air-supply to the generator is cut off.

Having thus described the nature of my invention and the manner of performing same, I would have it `understood that what I believe to be new, and therefore claim as my improve ments, in apparatus for the manufacture of airgas, 1s

l. The gas-'holder H3, tank H", rods I I, It', and I, in combination with the trigger J 3, pivoted bolt J, spring J5, rod E, having projection El, and bolt J provided with slots J 2 J, substantially as described, and for the purpose set forth.

2. The frame J, provided with iiat bolt J having slots J'l and J, spring-trigger J, pivoted bolt J spring J 5, in combination with rod E, provided with projections E2, substantially as specified.
